"Blend of Jean and Carlo"
The name Jeancarlo is commonly a male name.
Jeancarlo is a compound given name built from Jean, the French form of John, and Carlo, the Italian form of Charles. The two elements are established given names in their own right, and here they are joined and written as a single word rather than as the two-word Jean Carlo.
The pronunciation of Jeancarlo is jeen-KAR-loh.
